St. Peter is mentioned so often in the New Testament—in the Gospels, in the Acts of the Apostles, and in the Epistles of St. Paul—that we feel we know him better than any other person who figured prominently in the life of the Saviour. In all, his name appears 182 times. We have no knowledge of him prior to his conversion, save that he was a Galilean fisherman, from the village of Bethsaida or Capernaum. There is some evidence for supposing that Peter's brother Andrew and possibly Peter himself were followers of John the Baptist, and were therefore prepared for the appearance of the Messiah in their midst. We picture Peter as a shrewd and simple man, of great power for good, but now and again afflicted by sudden weakness and doubt, at least at the outset of his discipleship. After the death of the Saviour he manifested his primacy among the Apostles by his courage and strength. He was "the Rock" on which the Church was founded. It is perhaps Peter's capacity for growth that makes his story so inspiring to other erring humans. He reached the lowest depths on the night when he denied the Lord, then began the climb upward, to become bishop of Rome, martyr, and, finally, "keeper of the keys of Heaven."
Our first glimpse of Peter comes at the very beginning of Jesus' ministry. While He was walking along the shore of the Sea of Galilee, He saw two brothers, Simon Peter and Andrew, casting a net into the water. When He called to them, "Come, and I will make you fishers of men," they at once dropped their net to follow Him. A little later we learn that they visited the house where Peter's mother-in-law was suffering from a fever, and Jesus cured her. This was the first cure witnessed by Peter, but he was to see many miracles, for he stayed close to Jesus during the two years of His ministry. All the while he was listening, watching, questioning, learning, sometimes failing in perfect faith, but in the end full of strength and thoroughly prepared for his own years of missionary preaching.
Let us recall a few of the Biblical episodes in which Peter appears. We are told that after the miracle of the loaves and fishes, Jesus withdrew to the mountain to pray, and his disciples started to sail home across the Lake of Galilee. Suddenly they saw Him walking on the water, and, according to the account in Matthew, Jesus told them not to be afraid. It was Peter who said, "Lord, if it is Thou, bid me come to Thee over the water." Peter set out confidently, but suddenly grew afraid and began to sink, and Jesus stretched forth His hand to save him, saying, "O thou of little faith, why didst thou doubt?"
Then we have Peter's dramatic confession of faith, which occurred when Jesus and his followers had reached the villages of Caesarea Philippi. Jesus having asked the question, "Who do men say that I am?" there were various responses. Then Jesus turned to Peter and said, "But who do you say that I am?" and Peter answered firmly, "Thou art the Christ, son of the living God." (Matthew xvi, 13-18; Mark viii, 27-29; Luke ix, 18-20.) Then Jesus told him that his name would henceforth be Peter. In the Aramaic tongue which Jesus and his disciples spoke, the word was kepha, meaning rock. Jesus concluded with the prophetic words, "Thou art Peter, and upon this rock shall be built My church, and the gates of hell shall not prevail against it."
There seems to be no doubt that Peter was favored among the disciples. He was selected, with James and John, to accompany Jesus to the mountain, the scene of the Transfiguration, to be given a glimpse of His glory, and there heard God pronounce the words, "This is my beloved Son in whom I am well pleased."
After this, the group had gone down to Jerusalem, where Jesus began to prepare his disciples for the approaching end of his ministry on earth. Peter chided Him and could not bring himself to believe that the end was near. When all were gathered for the Last Supper, Peter declared his loyalty and devotion in these words, "Lord, with Thee I am ready to go both to prison and to death." It must have been in deep sorrow that Jesus answered that before cockcrow Peter would deny Him thrice. And as the tragic night unrolled, this prophecy came true. When Jesus was betrayed by Judas as he prayed in the Garden of Gethsemane, and was taken by soldiers to the Jewish high priest, Peter followed far behind, and sat half hidden in the courtyard of the temple during the proceedings. Pointed out as one of the disciples, Peter three times denied the accusation. But we know that he was forgiven, and when, after the Resurrection, Jesus manifested himself to his disciples, He signaled Peter out, and made him declare three times that he loved Him, paralleling the three times that Peter had denied Him. Finally, Jesus charged Peter, with dramatic brevity, "Feed my sheep." From that time on Peter became the acknowledged and responsible leader of the sect.
It was Peter who took the initiative in selecting a new Apostle in place of Judas, and he who performed the first miracle of healing. A lame beggar asked for money; Peter told him he had none, but in the name of Jesus the Nazarene bade him arise and walk. The beggar did as he was bidden, cured of his lameness. When, about two years after the Ascension, the spread of the new religion brought on the persecutions that culminated in the martyrdom of St. Stephen, many of the converts scattered or went into hiding. The Apostles stood their ground firmly in Jerusalem, where the Jewish temple had become the spearhead of opposition to them. Peter chose to preach in the outlying villages, farther and farther afield. In Samaria, where he preached and performed miracles, he was offered money by Simon Magus, a magician, if he would teach the secret of his occult powers. Peter rebuked the magician sternly, saying, "Keep thy money to thyself, to perish with thee, because thou hast thought that the gift of God may be purchased by money."
With his vigorous outspokenness, Peter inevitably came into conflict with the Jewish authorities, and twice the high priests had him arrested. We are told that he was miraculously freed of his prison chains, and astonished the other Apostles by suddenly appearing back among them. Peter now preached in the seaports of Joppa and Lydda, where he met men of many races, and in Caesarea, where he converted the first Gentile, a man named Cornelius. Realizing that the sect must win its greatest support from Gentiles, Peter helped to shape the early policy towards them. Its growing eminence led to his election as bishop of the see of Antioch. How long he remained there, or how or when he came to Rome, we do not know. The evidence seems to establish the fact that his last years were spent in Rome as bishop. The belief that he suffered martyrdom there during the reign of Nero in the same year as St. Paul is soundly based on the writings of three early Fathers, St. Irenaeus, Clement of Alexandria, and Tertullian. The only writings by St. Peter which have come down to us are his New Testament Epistles I and II, both of which are thought to have been written from Rome to the Christian converts of Asia Minor. The First Epistle is filled with admonitions to mutual helpfulness, charity, and humility, and in general outlines the duties of Christians in all aspects of life. At its conclusion (I Peter v, 13) Peter sends greetings from "the church which is at Babylon." This is accepted as further evidence that the letter was written from Rome, which in the Jewish usage of the time was called "Babylon." The second Epistle warns against false teachings, speaks of the Second Coming of the Lord, and ends with the beautiful doxology, "But grow in grace and knowledge of our Lord and Saviour, Jesus Christ. To him be the glory, both now and the day of eternity."
The latest archeological findings indicate that St. Peter's Church in Rome rises over the site of his tomb, as Pius XII announced at the close of the Holy Year of 1950. In the catacombs many wall writings have been found which link the names of St. Peter and St. Paul, showing that popular devotion to the two great Apostles began in very early times. Paintings of later date commonly depict Peter as a short, energetic man with curly hair and beard; in art his traditional emblems are a boat, keys, and a cock.
